Self-study
I am confused because the correct answer to this question seems like it's a necessary assumption and not a sufficient assumption, as the question stem would describe it to be. I generally regard necessary assumptions to be the "bare minimum" standard. It seems that "societies being geographically isolated enough not to have been influenced by any other society" only allows for, and does not guarantee, the conclusion to be drawn. When I really analyze the question I guess I could see how it's sufficient, but am I crazy to think that this reads so similarly to a necessary assumption? Is there a helpful technique for distinguishing the two in a situation like this?

I drink lots of water and basically have zero bladder. Have been that way since I was little. The first time I took the LSAT, I went to the bathroom three times during the timed test. It was ridiculous and very much interfered with my performance. However, the second time I took the LSAT I had no bathroom interruptions. Here’s what I did differently: First, do not eat fruit for breakfast. This may seem obvious but fruit has lots of water in it. I unfortunately did not take this into account when I ate an entire carton of blueberries for breakfast prior to my first sitting. Have a protein-based breakfast instead (protein bar, egg, etc). Second, drink one glass of water when you first wake up and drink nothing more (unless you have a medical condition requiring you to drink water more frequently, in which case you could try getting accommodations for breaks). It was way more manageable to test while a little thirsty (you forget about it) than to constantly think about how bad I needed to go and how much longer would I make it and omg i’m gunna pee my pants etc, etc. On that note, make sure to use the restroom before you go into the test room. Like if you haven’t gone yet or if the last time you went was a while ago do not walk into that test room. Fourth, do not drink coffee or espresso in the morning. I bought these mints infused with green tea powder and chocolate covered espresso beans from Peets. Worked fine. There’s a million ways to get your caffeine fix (don’t go overboard with caffeine pills though, they can be rly dangerous). Fifth, make sure you bring a sweatshirt (without a hood) and wear light pants to the test center. Being cold makes you need to go. (Even though its summer time, some test centers have the air conditioning blasting out of control.) If you do all of this you’ll be A1.
